Unsatisfactory service form Audi Bryanston Winnie Mandela Drive

I took my car in for a major service and this was done perfectly. But upon fetching my car I noted that there was no front wheel 'audi' cap , and now after hitting a pothole, I got a puncher. When I checked for my wheel spanner it is also missing. I am not happy with their service. I did email , call and even complained about this on the customer satisfaction survey, but this has not yet been solved.
